I ended up purchasing a ps4 with n4s. I rather have had something to play with friends with when I want, and something I can just pick up, have a few games of and put down.
I quite like it, seems a good bit of kit. I'm just going to wait for driveclub/the crew to come out and that's me set for a few months.
Ps3's second hand are going for 120/150quid depending on model. I just thought I'd pay the extra and get something that'll have some good titles later down the line.
